Given numbers are 759,913,428,550,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 759,913,428,550,978 is 109873067700.
Find LCM of 759,913,428,550,978 with Prime Factorization
| 2 | 759, 913, 428, 550, 978 |
| 3 | 759, 913, 214, 275, 489 |
| 11 | 253, 913, 214, 275, 163 |
| 23, 83, 214, 25, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 23 x 83 x 214 x 25 x 163 = 109873067700
Therefore, the lowest common multiple of 759,913,428,550,978 is 109873067700.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
759 x 913 x 428 x 550 x 978 = 159535694300400
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
759 : 1, 3, 11, 23, 33, 69, 253, 759
913 : 1, 11, 83, 913
428 : 1, 2, 4, 107, 214, 428
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 759,913,428,550,978, is 1.
Now, the common factors can be found like this.
759:3x 11x 23
913:11x 83
428:2x 2x 107
550:2x 5x 5x 11
978:2x 3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 11x 11 = 1452
Therefore, the value for common factors is 1452.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 159535694300400/(1x1452)
LCM = 159535694300400/1452
LCM = 109873067700
Thus, we can understand that the LCM of 759,913,428,550,978 is 109873067700.
